EAVING DEVICE.

Application filed October 30, 1922. Serial No. 597,998.

To all whom it may concern:

Be it, known that I, ROBERT E. KnEMERs, a citizen oftthe United States, residing at Portland,-in1the county of Multnomah and State of Oregon, have invented a new and useful Improvement in Paving Devices, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to paving devices as a class.

The object of my invention is to provide a paving device comprising metal plates which are secured in position upon planks and which device is also easily and quickly placed in position and removed therefrom. The device is intended primarily, and is particularly arranged and adapted, to be placed between and outside of the rails of railroads at their crossings over streets or highways, and to provide at such places a safe travellin course over and flush with the rails. It is also adapted as a pavement for bridges. While the device is well adapted to the places named, it may be used along any portion of railways. These objects, as well as other advantages, I attain by the construction, combination and arrangement of parts illustrated in the accompanying drawings which form a part hereof.

Fig. 1 is a plan View of a plate in secured position upon a plank, both broken away at one end.

Fig. 2 is a transverse sectional view of part of a rail track with plates in operative position upon supporting planks.

Fig. 3 is a transverse, sectional View of the constructive features of the device on the line 3-3 in Fig. 4, with added parts of track.

Fig. 4 is a sectional view of the arts illustrated in Fig. 3 on the line 4.4 t erein, and added parts of track.

Like characters refer to like parts in all views.

A plank 5, of convenient length, and of suitable other dimensions for construction purposes, is provided. Upon such plank sections, the plate 6 is secured. This plate may be flush with the ed es of the upper surface of the plank, or of esser length and width, toallow spaces between edges of the plates when in operative position. The plates are provided with a series of openmgs 7 to receive bolts 8 which extend downwardly through openings 9 in the plank 5 'ing 23, of a common type is shown in heads 11, resting upon the surface of the plate 6, or they may have heads countersunk in the late as shown by the'head 12 in Fig. 2. he heads may be either round or square. The bolts are retained in position to secure the plates rigidly upon the planks by means of nuts 13 upon their lower ends an within the recesses 10. The plate' is also provided with a series of openings 14 to receive spikes 15. The upper surface of the plate 6 is shown as checkered, but any other rough surface, such as grooved, channelled, corrugated and the like, ma be substituted or the surface made smooth if desired. The lanks, with the secured plates thereon, are rst made as shown and described, and are of varyin dimensions suitable to be laid as a whole etween rails and tracks where a pavement of this kind is intended to be fitted in place. In Figs. 234, railroad ties 16 are shown in place below rails 17 to which the rails are secured by spikes, as at 18. Below the ties is shown the 'ballast 19 of the usual road bed. In Fig. 4 guard rails 20 are shown secured to the track rails 17 by bolts 21. In the same figures the planks 5 are shown joined against the rails 17, or guard rails 20, except that along the inner-web and base surfaces of the rail, and joined to the adjacent plank 5, filler strips or blocks 22 may be laid to revent the lower part of the space from ling up with foreign substances. The upper part of the space is to allow travel courses for flanges of the wheels of cars when moving along the rails. The

spikes 15 are driven through the plate 0 enings 14, downwardly through the plan s 5 and into the ties 16 as illustrated, to secure the planks with their superimposed metal wearing surfaces in operative position as a paving device. The planks may be bolted instead of spiked to secure them in place if constructive features require it. Street av- 1g. 4, with plated lanks 5 secured between the pavement and t e rail.

It will now be seen that the sections of plank, prepared with the metal plates for wearing surface, can be made in any form and dimension required to'fit between parallel, diagonal switching, or cross tracks as may occur over a street crossin When thus prepared they can be secure in operative position as shown. lit is obvious that the (is that the planks, or any section,'can be quickly and easily removed to allow of repairs to the track or roadbed. A section ma then be relaid, unless the plank has split away in removal, and should this occur,

, its plate can be secured without diiiiculty u on a new plank section. This paving device may also be used to great advantage on bridges, where it may be secured in some convenient manner to the bridge beams. The ends of the planks, where they terminate between rails 'may be bevelled and the 1Eplates bent upon this portion, as shown in ig. 3, which will obviate the chances of ob ects depending from cars on the rails, engaging and injuring the paving sections, or causing accidents. In bridge work, where the under surface of the travel way is easily accessible, the planks of my device may be laid first, and the plates in convenient sections secured upon one or more of the planks as may be desired, without departing. from the principle of my invention. Should railroad tracks either settle or rise, in places where my paving device is laid, the pavement thus provided will adapt itself as a whole to such changed positions of track or roadbed, being necessarily a homogeneous part, and thus the travelled surface will always remain flush with the rails, which is an important feature. Having thus shown that'my device is new and useful, I claim l. A paving device having in combination, a plank member of convenient form, provide with a plurality of bolt openings therein, a metal plate member of convenient formprovided with a plurality of bolt openinee ao j ings therein opposite those in said first memher, and a plurality of bolts extending through the openings in said members prd vlded with means on each end thereof to allow the bolts to secure said plate rigidly upon the surface of the plank, said members thus fastened together being adapted to be laid between or adjacent to track rails or upon bridges and rigidly secured to ties or other parts of such structures in a desired position.v

2. A paving device having in combination, a plank member of convenient form, provided with a plurality of bolt openings therein, a metal plate member of convenient form provided with a plurality of bolt openings t erein opposite those in said first member, a plurality of bolts extending through the openings in said members provided with means on each end thereof to allow the bolts to secure said plate rigidly upon the surface of the plank, and means to secure said members thus fastened together to ties or other parts of a structure for whichthey are intended and in'desired positionwith relation to the travel .way thereof.

3. A pavement having in combination, a series of plank members of convenient forms, each provided with a plurality of bolt openings therein, a series of metal, plate members of convenient forms each provided with a plurality of bolt openings therein opposite those in the related first members, a plurality of bolts extending through the openings in said members provided with means on each end thereof to allow the bolts to secure said plates rigidly upon the surfaces of the related planks, and means to secure said members thus fastened together to ties or other parts of a structure for which they are intended and in desired positions with relation to the travel way thereof.
